In this paper, a two-stage resource allocation scheme is proposed to supervise interference and resource allocation while establishing a realistic scenario of three-tier heterogeneous network architecture. The scheme consists of two stages: in stage I, a two-level sub-channel allocation algorithm and a power control method based on the logarithmic function are applied to allocate resource for Macrocell and Picocells, guaranteeing the minimum system capacity by considering the power limitation and interference coordination; in stage II, an interference management approach based on K-means clustering is introduced to divide Femtocells into different clusters. Then, a prior sub-channel allocation algorithm is employed for Femtocells in diverse clusters to mitigate the interference and promote system performance. Simulation results show that the proposed scheme contributes to the enhancement of system throughput and spectrum efficiency while ensuring the system energy efficiency.展开更多

The preamble of the constitution enshrines the values of a socialist, secular and equality. The aim was to create a society, based on fair and equitable distribution of resources and bringing the weaker sections to the mainstream of the society. However with the entry of globalization rapid changes were being made in the structural policy. Markets started taking over from where the state left off. it has been two decades and half since the liberalization, privatization and globalization phase was ushered in. Subsequently, privatization of education is rampant in each part of education system of India. The main objective of this paper is to find out socio-educational inequality at higher education level and to explore the educational participation, attainment and performance of scheduled castes at higher education level. Basically, this study is an empirical and exploratory research. Data collection and analysis were done through the data triangulation methods in this research process.展开更多
